I think JMM could have beaten Hatton.
It would have been a great fight if it would have happened before Mayweather sent Hatton on a date with the ring post. That ring post destroyed lives and was a home wrecker! lol
Hatton was never the same after that, neither was his fan base. Now, we have the *******s.... (even worse). They too will disappear like that whore of a ring post that used and abused Hatton like it did.... it was embarrassing.
However, I would favor Hatton but think JMM would make it very interesting.
